Which speed indication of a hard disk drive typically suggests that the device is optimized for energy efficiency rather than performance?
5,400rpm
15,000rpm
10,000rpm
7,200rpm
A hard disk drive with a rotational speed of 5,400rpm is designed to conserve energy and provide a quieter operation, which is beneficial for environments sensitive to noise and less demanding in data transfer speeds, such as in certain consumer laptops or external backup drives. Higher rotational speeds like 7,200rpm or 10,000rpm indicate drives optimized for faster data access and higher performance, typically found in desktops or servers which require rapid data retrieval.
